HGST Deskstar 7K400 400GB SATA Drive

This new 3.5-inch internal hard drive offers 400GB of storage on a SATA 1.5Gb/s interface. It spins at 7200 RPM with an 8MB cache and an 8.5ms average seek time. The Fluid Dynamic Bearing motor supports quiet, reliable operation. It suits desktop PCs needing basic magnetic storage for archives or secondary data.

Check SATA Port and Bay Compatibility

Verify your motherboard provides a free SATA data port and that your power supply includes a SATA power connector. Ensure the chassis has an available 3.5-inch drive bay with mounting screws. Confirm the operating system can recognise a drive of this capacity without additional drivers.

Fits Standard 3.5-Inch Desktop Bays

The drive mounts in any standard 3.5-inch bay using four screws and connects via two cables. It requires no special cooling beyond normal case airflow. Using this mechanical drive for bulk files frees up faster solid-state storage for the operating system and active applications.

商品問答

Does the bare-drive HDS724040KLSA80 include cables or brackets, or must I buy them separately?

The drive is supplied as a bare unit only; SATA data and power cables plus any mounting screws or brackets need to be sourced separately.

The 400 GB 7200 RPM model is the only capacity listed — is it the right choice for a desktop needing a single OS and data volume?

With 400 GB, 7200 RPM speed and 8 MB cache it suits a primary desktop volume for operating system, applications and moderate data storage.

How does the 8.5 ms average seek time affect everyday desktop responsiveness?

An 8.5 ms seek time delivers typical mechanical-drive responsiveness for boot, application launch and file access in a standard desktop workload.
